Fix the timer to a wall in a covered location, sheltered from weather and splashing water; ambient temperature
between 0 and 50 °C. Do not install the timer outdoors or in underground valve box.
Before connecting the timer to the electrical power supply, install the 9V backup battery, which will ensure that the clock
setting and programme data will not get lost in case of a mains power failure. Open the snap-t cover of the battery pocket.
Pull out the cable (and the old battery, in case of a replacement). Connect or replace the battery. Reposition the cable and
the battery in the pocket and close the cover. If the back-up battery is missing or at, the message “ ” appears.

The Master Valve (main valve) is an optional safety valve, installed upstream of the line valves; it is opened auto-
matically so that the system is only powered while watering operations are in progress.
1
Pass the required electrical cables through the protective pipe. The recommended cross-section for all
cables is 1.5 mm
2
with a length of less than 350 m: above this limit, the cross-section needs to be increased.
2 Connect the cables to the relative valves (including the Master Valve if used).
3 Join the individual wires coming from any valve terminal with a wire from the water timer (common for the
valves).
4
Remove the cable protection cover by unscrewing the self-tapping screws and make the connections to the
water timer terminal board by inserting and tightening the ends which will have been stripped by 5-6 mm;
- the common wire coming from the valves to the terminal C,
-
the wire coming from the second terminal of each line valve to terminals from 1 to 4 (6if there are 6 lines),
- the wire coming from the second terminal of the Master Valve (if used) to the terminal MV.
If a control pump is used, connect the two terminals A1 and A2 of the relay coil to the terminals MV and C
respectively, and complete the connections.
The solenoid valves and relay used must operate at 24 VAC - if a pump is used, this must only be connected
via a relay which will operate a contactor.
The Master Valve is used as an alternative to the pump relay and vice versa.
5 Attach the water timer to the bracket.
6 Insert the stripped ends (stripped by at least 5-6 mm) of the transformer cable into the two terminals AC.
7 Attach and secure the cover using the two 2.9x13 self-tapping screws.
8 Plug the transformer into the power socket.
Only use the transformer supplied with the water timer.

CYCLICAL SCHEDULE
The CYCLICAL SCHEDULE function allows Programme Aor Bto be repeated at time intervals equal to the number of set
days. This type of programming is carried out as an alternative to the weekly schedule but programmes A and B are
independent:this means that Programme Acan be associated with a WEEKLY SCHEDULE while Programme Bcan be associa-
ted with a CYCLICAL SCHEDULE.
- repeatedly press Aor Buntil the watering day settingis reached
- press a number of times right arrow until the cyclical schedule symbol appears
- press ENTER, appears OK
- to set the number of days in the interval (from 1 to 12), press the arrows
- press ENTER to conrm the setting; the rst watering operation will take place on the same day as the setting
- press Aand Bat the same time to exit the programming
- to cancel the CYCLICAL SCHEDULE, repeat the steps and set the day interval duration to .
Example. If Programme Bis carried out EVERY THURSDAY, therefore every 7 DAYS (WEEKLY SCHEDULE) but needs to be carri-
ed out more frequently, it can be set to every 3 DAYS (for example, SATURDAY 1 March....MONDAY 3 March....THURSDAY 6
March... and soon..) using the CYCLICAL SCHEDULE function.
If the CYCLICAL SCHEDULE is cancelled, the water timer suggests the previous WEEKLY SCHEDULE associated with the
programme (Programme Bis once again associated with THURSDAY).

SEMI-AUTOMATIC MODE
The SEMI-AUTOMATIC mode allows a single watering cycle to be started immediately in accordance with the run
time set in one of the Programmes Aor B; this is useful in providing additional watering if necessary.
The opening run times of the valves are those set in Programme Aor B, while the function does not consider:
- START TIMES (watering start times);
- CYCLICAL/WEEKLY SCHEDULE (on which days Programme activation was planned) since watering is imme-
diate.
- press the arrows once at the same time (SEMI-AUTOMATIC mode of Programme A) or twice (SEMI-
AUTOMATIC mode of Programme B)
- Press ENTER to activate the selected programme or suspend it if previously activated. = programme
activated, = programme suspended.
- Press Aand Bat the same time to exit the function.
In SEMI-AUTOMATIC mode the display will show all the numbers of the active valves, with the cursor on the
active valve; if it is ashing this indicates that the valve is activated by Programme A, if it is permanently on it
indicates that the valve is activated by Programme Bor that it is activated in the Manual or Test mode.
SEMI-AUTOMATIC mode is not permitted if MANUAL or TEST modes are active.

% FUNCTION
The BUDGET function enables an easy and swift adjustment of the selected programme duration to changing
climatic conditions; times can be varied without diculty: either reduced to 0 (this is the quickest way to deacti-
vate the set programme) or increased to 200%, without any need to change the watering duration selected in
the programmes. 100% corresponds to the duration set when the timer is programmed. The adjustment is inde-
pendent for each programme (Aand B).
- press the left arrow and the middle button (%): the symbols % and Awill appear
- press ENTER to activate the selection of a percentage for programme A
- use the arrows to select the percentage (e.g. from 100% to 150%)
- press ENTER to conrm the setting for programme A

ENABLING THE MASTER VALVE
The cut o valve (Master Valve) or a supply pump (through the control relay of the relative contactor) allow water to
be added to the system only when required for watering needs.
Master Valve: is an additional valve which is tted upstream of the valves associated with the various watering areas;
it is only opened by Cometa® during watering operations.
Supply pump: if the water supply comes from a well, tank or cistern, the pump is needed to ensure the system has
enough pressure. Cometa® is therefore able to control pump activation only during watering operations.
If the system has a Master Valve, it must be enabled as follows:
- press Aor Bonce
- press right arrow until the cursor moves to
- to activate the Master Valvesetting, press ENTER, appears OK
- press right arrow to activate or deactivate the Master Valve. = Master Valve enabled, = Master Valve
NOT enabled
- Press ENTER to conrm the setting.
- Press Aand Bat the same time to exit the function.
